For a bolted assembly with 8 bolts, the stiffness of each bolt is k_b = 1.1 N/mm and the stiffness of the members is k_m = 2.8 N/mm at each bolt location. The joint is subject to occasional disassembly for maintenance and should be preloaded accordingly (to 75% of the proof stress). Assume the external load is equally distributed to all the bolts. It has been determined to use M6 × 1 class 5.8 bolts with rolled threads. Determine the maximum safe working load that both limits the stress in the bolts to be below the proof stress and ensures that the members do not come out of compression. Express your answer in units of kilonewtons.
